In 2006, the former Blackhawk helicopter pilot beat charges that could have landed him in a military prison for life, with a former defense attorney saying the Army dropped two separate rape charges against Goulet in Hawaii. And Santa Cruz County officials said Thursday they were investigating a previously unknown molestation case against the 35-year-old former barista, adding to a growing list of past sex and violence charges.

"These officers possessed limited information about Goulet. They were investigating a misdemeanor case," Santa Cruz County Sheriff Phil Wowak said Thursday. "They had no information that led them to believe that they were in danger or that Goulet, at that time, was a danger to them."

First reported by the Honolulu Star-Advertiser, the new revelations add to Goulet's history of peeping activity, with misdemeanor convictions in San Diego, Portland, Ore., and Berkeley.

Friday, Goulet allegedly broke into the home of a co-worker after a night of drinking in an apparent sex assault attempt, an incident that set in motion Tuesday's shooting deaths of two Santa Cruz police detectives.

That allegation -- which occurred after a night of after-work drinks, sources familiar with the incident say -- mirrors the facts behind a rape charge brought against Goulet while he served in the military. Army officials later agreed to drop all charges under a plea deal, and did not immediately respond to a request seeking comment.

Former Goulet defense attorney Don Wilkerson in Hawaii said the first charges stemmed from an incident just days after Goulet began serving at Wheeler Army Airfield in Honolulu.

A group of soldiers threw a party, which was attended by a young female officer who lived off base. After going home, locking her doors and going to bed, Goulet allegedly attacked her.

"The first one happened within one week of his arrival here," Wilkerson said. "Mr. Goulet was accused of crawling in through her bathroom window and raping her."

Rather than lock up Goulet, military brass grounded him and ordered him not to leave the base. He was assigned to watch over barracks.

Several months later, a group of military personnel in one of Goulet's barracks threw a party the night before deploying to Iraq. After that party, Goulet allegedly raped a second female officer.

After the second allegation, the military locked up Goulet in Naval Brig Ford Island in the middle of Pearl Harbor, Wilkerson said. Goulet stayed there for several months.

Lack of consent was not an issue in either case, Wilkerson said. However, there were identification issues in the first and credibility issues in the second.

Wilkerson negotiated a plea deal that saw the Army drop the case in exchange for an "other than honorable" discharge.

Military records confirm Goulet was assigned to Hawaii in April 2006. He was discharged in early 2007, and immediately embarked for Portland, Ore., records show.

Later that year, Goulet was arrested over a peeping incident and subsequent brawl, during which a gun was discharged. Beaten badly by the victim's boyfriend -- as well as the victim herself, who wielded a shelf -- a jury acquitted Goulet of four felonies, finding him guilty of two misdemeanors.

Portland investigators found evidence that Goulet secretly taped another victim as well. He admitted on the stand to video recording women. People close to the case, who did not want to be identified, said the jury did not see what everyone else connected to the case did -- that's something was wrong with Goulet.

Though given probation on the misdemeanors and not required to register as a sex offender, Goulet was ordered to undergo treatment and submit to polygraph tests and searches of his computers and cellphones. But Goulet rejected treatment and fought with his female probation officer, even refusing to leave the premises and peering into her office windows after one meeting was cut short.

Rather than comply with the terms of probation, Goulet chose jail instead. Judge Eric Bloch took the highly unusual step of giving him maximum misdemeanor penalties, and strung them back-to-back.

Bloch also refused to reduce the sentence, which is standard in many Oregon cases. Goulet served two years in jail.

"I felt it was my duty to impose the maximum penalty within my power because I was very concerned that he was a risk to the community," Bloch told the Oregonian newspaper this week. "He thought his behavior was normal, and I was very clear to him that I thought his behavior was not normal and not appropriate."
